However, before getting to those fixes, let's see what causes the appearance of those white lines on the iPhone screen.

Part 1. What Causes White Lines on iPhone Screen?

There can be many reasons that can cause white lines on iPhone screens, including both hardware and software ones. Let's have a look!

  • Loose Flex Cables: A bad connection between the flex cable and logic board is the first thing that comes to mind if there are white lines on the iPhone screen.

  • Electrostatic Discharge: Undue electrostatic discharge is also a significant cause of these disturbing white lines on your iPhone's screen.

  • Damaged Screen: Dropping the iPhone on a hard surface may damage the screen, forming cracks that may appear as white lines.

  • Loose LCD Cable: If the white lines appear on the iPhone screen just after changing the LCD cable, then the culprit is most likely the loose connection of the new LCD cable.

  • Water Damage: Water can disturb the internal functioning of the iPhone, so white lines on iPhone screen can also appear after dropping the iPhone in the water. Water droplets or dirt can also be trapped between the screen and glass protector, mimicking those white lines.

  • iOS Bugs/Software Issues: Many iPhone bugs are out there, which can result in those white lines.

Regardless of the reason, here are several ways to fix the white lines on iPhone screen.

Part 2. How Do You Fix the White Lines on Your Phone Screen?

Here are the steps to check the iPhone battery cycle count:

Go to Settings > Privacy > Analytics & Improvement > Analytics Data.
